Move wymeditor javascript to after application.

Wymeditor javascripts use functionality included by the
'refinery/application' manifest. Therefore, it must be included
afterwards.

This change in conjunction with my other pull request to
parndt/refinerycms-wymeditor fixes a problem where ajax pagination would
trigger two ajax requests when clicking a page change rather than just
the desired one.

This was because both wymeditor and refinery/application asset pipelines
were including refinery/admin, which then triggered init pagination
twice, which resulted in two identical handlers firing.
