Searching on Common interest is case sensitive

When searching profiles, search term is case-sensitive and should be case-insensitive

Click on Profile -> Search
Select Common interest and enter a term you know will be found, but use a different case
Click Search - no results found

Now enter the same term in the correct case and click Search
Now results display

E.g.:

Searched on rollins because a couple of users had this as a favorite author
No results found
Entered Rollins and now I have results
