[#1548] Refactor profile deletion flow

[pi-sigma]

Taiga: #1548

Refactor profile deletion flow:

• Before deleting, check if there are plans associated with the user profile and warn user, if appropriate
• After check, delete user immediately instead of deactivating and waiting 14 days

• Please update the name of the form as well ( deactivate-form ) in order to be more clear what we are doing here.
• Update the User's deactivated_on field - clear enough that this is deprecated
• Do a search for "deactivate", there are a couple of spots that could be updated as well

Some small remarks and this can be merged.

Please update the form name ("deactivate-form" is not representative) and in my opinion the help-text of the User's model field (deactivated_on) should mention that this is deprecated since the account is now deleted.

@vaszig can this be approved now? Would like to get this into the v1.8 release
