[Data collection] Restore position to last active task when restoring from draft

[shobhitagarwal1612]

Fixes #2832

Reuses currentTaskId mechanism to set the initial task position when restoring from draft.

draft-position.webm

@sufyanAbbasi there is some weirdness with task sequence when moving to previous task from restored position. Do you have any ideas?

@sufyanAbbasi @gino-m PTAL?
