UI will allow user to attempt to create a subscription if they have Create permission but not Browse

[DHaussermann]

It was previously established that creating a subscription for a project would require both "Browse Project" and "Create Project" This is the correct functionality.

The Bug is that If users have Create but not Browse (definitely an edge case), the project still shown in the drop down and they can attempt to make a subscription. On save they will see modification error: failed to get project "<nane>": - No project could be found with key '<name>'.

Since the save is not possible, the project should be hidden from the drop down.
