Title: [minor] Remove dash from possible characters in a randomString

This helps avoid cases where a randomString used in a cli tool such as jitsu confuses options parsers by having the dash at the beginning. For example,

-6sOkYcS_qoYMA4O

is easily misinterpreted.

One thing to point out, though, is that these changes mean we're now technically generating base63 strings. I'm not sure what ramifications, if any, this has.
