push: change submodule default to check

When working with submodules, it is easy to forget to push the submodules.
The setting 'check', which checks if any existing submodule is present on
at least one remote of the submodule remotes, is designed to prevent this
mistake.

Flipping the default to check for submodules is safer than the current
default of ignoring submodules while pushing.
