Revisit stored procedure detection

Browse Source 
This commit revisits the improved detection algorithm for stored
procedure as, unfortunately, certain JDBC drivers do not support
the documented pattern for schema and procedure name.

To work around this limitation, this commit applies the escaping of
wildcard characters to the case where multiple procedures have been
found for a given search.

Closes gh-32295
