quickly share creates GPG key with no email address and subsequently fails

Binary package hint: quickly

When using quickly share for the first time, quickly generates a GPG key. However, this key does not include an email address and quickly subsequently fails with the following error:

Your gpg key has been create. You have to upload it to Launchpad. Guidance is provided in Launchpad help. Press any key once done.
Traceback (most recent call last):
  File "/usr/share/quickly/templates/ubuntu-application/share.py", line 107, in <module>
    keyid = quicklyutils.get_right_gpg_key_id(launchpad)
  File "/usr/share/quickly/templates/ubuntu-application/internal/quicklyutils.py", line 375, in get_right_gpg_key_id
    os.putenv('DEBEMAIL', email)
TypeError: putenv() argument 2 must be string, not None
ERROR: share command failed

Steps to reproduce:
1. Create a project using quickly on a machine that has no GPG keys stored
2. Run quickly share in the project folder
3. Quickly generates a GPG key with no email address (e.g. John Smith <None>)
4. Register the key with Launchpad
5. Press ENTER in the window where "quickly share" is running to proceed

Actual behaviour
Quickly crashes

Expected behaviour
Quickly should request an email address from the user so that the created GPG key includes that address.
