fix: Emit password recovery event from verifyOtp when otp type is rec…

…overy (#829)

## What kind of change does this PR introduce?

Bug fix

## What is the current behavior?

Currently when the user goes through the password recovery flow via OTP
and calls the `verifyOtp()` method, the `SIGNED_IN` auth event is
emitted instead of `PASSWORD_RECOVERY` event.

## What is the new behavior?

When the user goes through the password recovery flow using email OTP,
the `PASSWORD_RECOVERY` event is emitted.

## Additional context

A Flutter SDK user reported this, and thought it probably makes sense to
bring it to the JS client as well.
