We were using the existance of OPTIONS_CALENDAR_SYNC in the
bundle to indicate that syncing was possible, and it's value
to indicate whether automatic syncing should be enabled.
This is misleading.
Now, we check the serviceInfo for the account type to figure
out if sync calendar and contacts is possible, and use the
options passed in to indicate whether or not it should be
automatic.
