[#15] Remove 'action' URL param after logging in
This small PR removes the ?action=login
search param from the URL after logging in.
How to Test
- Log out
- Try to access a sub-page, such as
http://localhost/data-sources

- Verify that the
action
param gets removed from the URL after the page fully loads
