Stage 7 of clang compiler warning patches.

[ethoms]

Stage 7:

Fixes a objc-method-access warning. The method is no longer in use, so I commented it out and made a TODO note to remove redundant methods.

[extrafu]

This method is used by the SOGo extensions for Thunderbird.

OK, sorry about that, never thought about Thunderbird plugin. I'll try to rethink this one. There is another objc-method-access in this file that i also could not clear. So thees are the only 2 I can't clear so far. below is the clang warnings:

SOGoMailAccounts.m:227:37: error: instance method '-contentAsDOMDocument' not found (return type defaults to 'id') [-Werror,-Wobjc-method-access]
