Issue:
custom copr project not working
When triggering packit copr-build with project specified, it sets the project name to something else - dhodovsk/packit-cli-hello-world-master and then fails with `ERROR    Request wasn't successful, there is probably a bug in the API code.`

Packit config
```
[dhodovsk@shiny hello-world]$ cat .packit.yaml 
---
specfile_path: hello.spec
jobs:
- job: copr_build
  trigger: pull_request
  owner: dhodovsk
  project: packit
  metadata:
    targets:
    - fedora-all
```

First copr run:
```
[dhodovsk@shiny hello-world]$ packit copr-build 
Packit 0.8.1 is being used.
Input is a directory: /home/dhodovsk/repos/github.com/packit-service/hello-world
Input directory is an upstream repository.
SRPM is /home/dhodovsk/repos/github.com/packit-service/hello-world/hello-0.72-1.fc30.src.rpm
Copr project dhodovsk/packit-cli-hello-world-master not found. Creating new.
ERROR    Request wasn't successful, there is probably a bug in the API code.
Unexpected exception occurred,
