Bugfix: Hard coded schema name in WCC install check
Bugfix: Hard coded schema name in WCC install check

JIRA: MADLIB-1177

WCC install check sql file had madlib hard coded as the schema name.
This commit removes the schema name altogether, since install-check
anyway sets the schema name in the search path at the beginning.

Closes #199
