There are no reason to check the return values for these functions
as the string passed as an argument will be set to an empty string
if it false. An empty string is a valid option in these instances.
Coverity warnings fixed:

3. check_return: Calling getAlias without checking return value (as is done elsewhere 8 out of 10 times).
CID 316557 (1 of 1): Unchecked return value (CHECKED_RETURN)
8. check_return: Calling getAlias without checking return value (as is done elsewhere 8 out of 10 times).
