Parser: Disable commafy for magic variables for month and day

Parser: Disable commafy for magic variables for month and day

In Parser#getVariableValue for the following magic variables
Language#formatNum was called without commafy parameter:

currentmonth, currentmonth1, currentday, currentday2, localmonth,
localmonth1, localday, localday2

The default value for formatNum nocommafy is false, meaning formatNum
will do commafication. For the above context, commafy is not needed
since the passed values are often month values like 02, 03 etc.
Commafy is noop on this values.

Explicitly pass false value for formatNum's nocommafy argument.
Language#formatNum method documentation for nocommafy also recommends
setting it true in case of dates.
