[Bug] [iOS] Email ComposeAsync not awaited correctly

[elicul]

Description

Email Compose Async API is async, however, it immediately returns despite not having completed the Email operation.
This is a problem, because when you show the compose email screen to the user it immediately dissapears and the user is not able to send the email.

Steps to Reproduce

1. Call await Email.ComposeAsync(emailMessage)

Expected Behavior

Call should block until user is able to send the email or cancel the operation.

Actual Behavior

The execution immediately proceeds.

Basic Information

• Version with issue:
  iOS: iOS15.1

I am unable to reproduce this on my device. When I send an email it works just fine and brings up the screen....

This should be fixed in the current version (by #1846)
