Since `set -e` is enabled, when `commit.gpgsign` is not set the
`git config` command would show an error. Given that it is technically
not ignored, the subshell would exit.

With this change, the `commit.gpgsign` setting is properly tested
by doing the fallback test if the command fails, so no exit status
code ends up quiting the subshell.

This change still supports CLI 1, but shows a deprecation warning
on the first run of `opswd`. Support for CLI 1 shall be removed
in the near future.

Closes #9600

BREAKING CHANGE: we've updated the aliases that run `rake` to use
`rails` instead because that's how they are run since Rails v5.
The old `rake` aliases can still be run by using the `rk` prefix
(e.g. the `rake test` alias has been changed from `rt` to `rkt`).
