Nicholas Nethercote 1a6f1a62fa Bug 1387381 - Remove nsXPIDLString local variables. r=erahm. 
nsXPIDLStrings are marked as VOIDED upon initialization. Most of these local
nsXPIDLString variables are immediately set via getter_Copies(), which will
either assign a string value (using Adopt()) or do SetIsVoid(). These can be
trivially converted to nsString, which will get the same treatment.

The patch suitably converts the remaining nsXPIDLString local variable as well.
