Municipal user logged out after trying to create site outside municipality

[atomtay]

Describe the bug
When a municipal user tries to create a development outside of their municipality (say, a Cambridge user tries to add a development in Acton), instead of displaying an error the user is logged out.

Steps to reproduce

1. Log in as a municipal user
2. Click "Create Development" and set the lat/long outside of the assigned municipality
3. Submit the development by clicking "Create Development"
4. An error will briefly appear, but then the user will be quickly logged out.

Expected behavior
The error message should appear, the user should stay signed in, and the development still should not go through.
