fixed issues.

1. Issue with routes
	There was issue with devise scoped routes

2. Strip API key 
	Strip API key was expired so created new test account on Strip & used API key from that account

3. Data type issue - location_id column in transactions table  
  Location_id column in transactions was of type string but it should be of type integer
  Added migration to change column data type
  We could have achieved this by type casting but since its a foreign key we might need to index it depending on our requirement. 
  In-case of indexing integer indexing is much faster than of string.

4. Fixed juery.ui loading issue 

5. rufus_scheduler gem version issue fixed. It is now locked at '2.0.24' as latest version doest not support start_new method

6. Gem state_select was using the form git which wasn't working. Removed the git url.
