Probably incorrect usage of a single equals in a condition in fundraiser_sustainers_tokens_alter()

 - Replaced a single equals assignment with double equals and made it match the style of the other hook_tokens_alter() functions. Specifically borrows this change from fundraiser_commerce_tokens_alter().

My guess is this would run multiple times (once for each context type) and overwrite itself each time. Now it will only run during the donation context type.


This is the offending line.
