Add assisted dialing indicators to the old call log.

Modify the call log grouping strategy. The strategy is as follows:

When comparing the current group to the next candidate to add to that group,
if the assisted dialing feature tag differs between the two, create a new
group.

Thus, if a call has other features like wifi or hd, we ignore those features
when making grouping decisions.
