Issue: Issue with one-character directory names
### Description

Selecting and opening _anything_ using Telescope leads to an error `E5108 ... We couldn't mkdir: /Users/.local`.  It seems that this stems from the function `action_state.get_current_history()`, but I'm not sure what is happening.  Opening up Telescope to use it seems fine, and `:checkhealth telescope` doesn't flag anything, but when I try to use it to do anything, it errors.

This happens for me even with the most minimal possible config, as provided.  I really have no idea what could be going on.  It shouldn't be doing anything in`/Users/.local`. This directory doesn't exist, and I don't think it should be trying to make it.  Instead it should probably be trying to access something in `/Users/myusername/.local`, I imagine, since I think that's the correct default location on macOS.  For instance, when I run `:echo stdpath("data")` I get back `/Users/myusername/.local/share/nvim`.

- Is there some new recently added option for configuring the where the .local directory should be?  Is there perhaps an error in the error message itself?
- I'll note I updated Telescope for the first time in a little while (I don't know what version I am coming from before, but I just installed things fresh on a new computer in February, so it wasn't very old, but I just updated to the most recent, and this bug started).

I wish I could troubleshoot further but I'm a little lost.  Any help would be appreciated!

**Edit:** my username is one character long. It seems this is causing the issue. For some reason for any one-character directory like `/Users/x/.local` it gets interpreted as `/Users/.local` by plenary.path, somehow.

### Neovim version

```markdown
NVIM v0.6.1
Build type: Release
LuaJIT 2.1.0-beta3
Compiled by brew@HMBRW-A-001-M1-004.local
```


### Operating system and version

macOS 12.3.1 (21E258)

### checkhealth telescope

```markdown
telescope: require("telescope.health").check()
========================================================================
## Checking for required plugins
  - OK: plenary installed.
  - OK: nvim-treesitter installed.

## Checking external dependencies
  - OK: rg: found ripgrep 13.0.0
  - OK: fd: found fd 8.3.2

## ===== Installed extensions =====
```


### Steps to reproduce

1. run `nvim -nu minimal.lua` (it is the absolute most minimal minimal config; no additional plugins or extensions are needed)
2. in nvim open any telescope picker, for instance run `:Telescope`
3. select anything in the Results list, for instance, `buffers`, and press <kbd>enter</kbd>

### Expected behavior

The selected item should open.  

For instance, if you ran `:Telescope` and selected `buffers`, you should see the buffers picker.  If you ran `:Telescope find_files` and selected a file, that file should open.

### Actual behavior

No matter what item I am selecting, whether it's a file from the `find_files`, or a telescope command from `:Telescope`, I get the same following error:

end
