Start sharesheet in the same profile instead of switching to other profile.

Instead of starting the sharesheet in the other profile when
choosing the "Switch to work"/"Switch to personal" button,
we now start the sharesheet in the same profile with the other tab
selected.

For example, we're in the personal profile and share something
via an app that uses its own sharing logic. That shows the
"Switch to work" button and when we press it, we now start
the sharesheet in the personal profile with the work tab selected.

The reason for this is to avoid user confusion when they go back
to the personal tab and it shows an empty state screen due to
lack of cross-profile intents.
