* Added in code changes that now properly increment the Untitled Query SQL Lab tab names. All that is left is to add tests to make sure that the function works correctly
* Updated the code so that it adds to the untitled_query_numbers variable only if the character after the string 'Untitled Query ' is a number. This prevents any issues when trying to get the maximum value in the list.
