push: test that --recurse-submodules on command line overrides config

t5531 only checked that the push.recurseSubmodules config option was
overridden by passing --recurse-submodules=check on the command
line.  Add new tests for overriding with --recurse-submodules=no,
--no-recurse-submodules and --recurse-submodules=push too.

Also correct minor typo in test commit message.
