Streamline activity start flow

Refactor activity start logic by moving the similar operations
together and remove code duplications.

The reusable task is selected in earlier stage, so that some
permission and security check could be performed before manipulating
the task (reparenting or finishing activities).

Also fix two activity start cases that didn't work as expected.
