Exception when both Project + Component is selected in groups

[ghubz]

Describe the issue

When editing a group, if you select both a Project and a Component then the following exception is given

Exception Type:	ValueError
Exception Value: 'GroupForm' has no field named 'project'.
Exception Location:	/home/weblate/weblate-env/lib/python3.7/site-packages/django/forms/forms.py, line 344, in add_error
Python Executable:	/usr/bin/uwsgi-core
Python Version:	3.7.3
Python Path:	
['/',
 '/home/weblate/weblate-env/lib/python3.7/site-packages/git/ext/gitdb',

{project: [ValidationError(['This is not used when a component is selected.'])]}
Unhandled 'GroupForm' has no field named 'project'.


### I already tried

- [X] I've read and searched [the documentation](https://docs.weblate.org/).
- [X] I've searched for similar issues in this repository.

### Steps to reproduce the behavior

1. Create a new group or edit an existing one
2. Select a project from the list
3. Select a component from the list (doesn't matter if it's under that project or another)

### Expected behavior

It is expected to either get a user friendly error in case that is not supported or save successfully. 

You should be able to allow access to specific Projects and Components. One might want to grant access to Project A but only component X of Project B. Now this doesn't seem to be possible.

### Screenshots
