Do not return intent if resolved to browser activity

Intent to switch from web to app should only be provided if intent is
resolved to non-browser activity. FLAG_ACTIVITY_REQUIRE_NON_BROWSER was
previously used to accomplish this, but this flag only throws an
exception when startActivity is called and still returns the browser
when Intent#startActivity is called.

Changes also resolves activities as a user to assure app does not open
in another user's account.
