Date with empty 'Repeats # Weeks' and "Repeats Every # of Days" validation needed

Thanks for reporting the bug and the patch, lets see what the testbot says.

Thanks for reolling the patch. This fixes the paths, see https://www.drupal.org/patch/create for details.

@dev11235 a trick if you're creating the patch from git within the a whole website is use the --relative flag. The proper way would be to get the changes on the git repo for the project as @DamienMcKenna mentioned above but if you're on the dev branch already updated the git diff --relative > name.patch is easier from with the project directory.

Also, I've done that type of patch by accident a bunch of times! Still trying to catch myself, probably will do it again.

@dev11235, the automated tests are showing a failure when INTERVAL key doesn't exist.

Undefined index: INTERVAL

Looks like this needs a minor re-roll as well because of some single quote string changes in another patch.

This looks great, I could see maybe just doing an !empty() but it would limit other values that "falsey", so this isset() is probably the way to go.

Moving this to a normal issue priority because it's a bug. Minor is more like typos or micro-optimizations.

Thanks. Committed.
