D19559: Explicitly delete MailWebEnginePage to avoid crash on KMail exit or viewer window close

[Daniel Vrátil]

  Now that I think about it, wouldn't it be cleaner if the `QWebEngineProfile` was instantiated inside of `MailWebEnginePage` and the page would be set as a parent for the profile? That way the profile would be destroyed automatically by Qt, but after `MailWebEnginePage` destructor, so still (and always!) in the correct order...could you test it, please?
