LP1958163 Bootstrap Opac: the 'Request a Card' link.

This fixes the 'Request a Card' link which displays in the bootstrap opac
 regardless of the 'Allow Patron Self-Registration' library setting in both
the login page and the login modal.

To Test:
1. Click on My Account in the Bootstrap Opac to open the login modal.
   Notice the Request a Card link.  Click Login without adding a barcode
   or pin# to see the login page with its link.
2. Set the Allow Patron Self_Registration library setting to false for the
   Consortium.
3. Repeat 1, and notice that the link still displays.
4. Apply the patch.
5. Now the link should not be visible in both forms.
6. Set the library setting to true, to verify that the link does display.
