Bug 20223: Merge members-menu and circ-menu inc files

Bug 20223: Merge members-menu and circ-menu inc files

This patch removes members-menu.inc and replaces the last functional use
of it with a call to circ-menu.inc.

An invalid use of members-menu.inc has been removed from member.tt.

To test, apply the patch and open a patron record for editing. The
sidebar menu should look correct and all sidebar links should work
correctly.

View the patrons home page and confirm that nothing has broken.

Search the Koha codebase for references to members-menu.inc. There
should be none.
