Replace "Show QR Code" in account menu with "Open Profile" action

When you just want to share or view your own profile, the UX has proven
to be a bit confusing. You could try to scroll to find a previous
message of yours, or hopelessly go down the rabbithole of settings (none
of which provide a copyable user ID currently.) Lets cut down on the
slack by providing a way to instantly open your profile from anywhere.

This replaces the "Show QR Code" action because this is duplicative
within the profile itself.
