Fixed profile count

Closes: #9721

Description of Changes

• Adds migration script to fix all profile counts Fixes login in 2 places:
  1. Due to the isolation level, since we were updating the user and the profile_count (which depended on the user) in the same transaction, the Read Committed isolation level did not read the state of the DB at the time of the command, but instead the state before the transaction started.
  2. When existing user joins a community, it now handles with a incrementProfile

Test Plan

For both fixes, check the before and after on some community (say we are testing the skale-testing community. We would check http://localhost:8080/skale-testing/members?tab=all-members).

Testing the two fixes:

1. Create a user and join any community from the "Join community button". Check that this member count has incremented. (corresponds with fix 1)
2. Sign in on a scoped page (say http://localhost:8080/skale-testing/dydx). This will automatically join you to a community and should increment the member count.
