Fix email failure bugs

[GuySartorelli]

This PR fixes two related bugs.

For both bugs, this PR logs the error, but lets code execution continue
Note that there are two ways this exception can occur:

1. admin_url is not a valid email address, so RfcComplianceException is thrown
2. Something fails in symfony mailer while actually sending the email, so TransportExceptionInterface is thrown

Bug one

• Cannot update member password when email fails to send in live mode #11034

If there's an exception thrown when trying to send an email to a user in live mode when their password has been changed, the new password does not get saved.

Bug two

No issue open

When using the password recovery functionality ("I've lost my password"), if an exception is thrown when trying to send the recovery email, the whole page just breaks.

Instead of that, the user should be given a user-friendly error message, and the cause of the error should be logged.

Notes

• With bug one specifically, there is some weird side-effect to logging the error which causes the success toast to be red (so it looks like a failure toast), and the page doesn't reload. But the new password is saved, so I'm raising a separate issue to look into that side effect. The bug this PR fixes is about saving the password value, and that bug is fixed with this PR.

Replicated both bugs locally and tested patch for both, works good. Just need to update the translation file
