User is now able to edit other users' information (#168). Also updated search so that the user can find an issue by number (via '#45', for example).
Fixed failing tests pertaining to change from 'update' to 'updateIssue'.
Added tests for new search capabilities.
Added tests for or post /users/edit.
Added test for making sure issues aren't updated when updating a user when the names haven't changed.
Added baseRepository.save tests for when a query is given.
