datalib:get_my_courses() - fix SQL compat Oracle - MDL-12427

Browse Source 
One of the SQL queries in gmc is concatenating ctx.path with an id field.
Oracle barfs at the idea of casting the numeric id - so we CAST() it
explicitly, lest there be any confusion.

Credit for the fix to Dennis Rochford <[email protected]>
