PM-1257 - handle wipro users payout

[vas3a]

https://topcoder.atlassian.net/browse/PM-1257

• modifies the migration file from when we truncated user_payment_methods to:
  • drop user_default_payment_method table
  • delete everything in user_payment_methods table, except users that have a payment method of either "Trolley" or "wipro payroll".
  • NOTE: this will not run in dev. I'll set the check-sum for the migration in the migration table, otherwise the migration will be out-of-sync.
• when new payment (winning) is made for payroll (wipro user), sets the wipro payroll payment method for the user (if not already set)
• prevents wipro user from fetching trolley portal link (so user can't fetch via direct call either)

correctness
The check for user.email.toLowerCase().indexOf('@wipro.com') > -1 could be improved for clarity and correctness by using user.email.toLowerCase().endsWith('@wipro.com'). This ensures that only emails ending with @wipro.com are matched, avoiding potential false positives.
