Remove deprecated is_method_error code

The is_method_error() function is no longer needed, instead a
try-catch block should be used instead.
Reference:
https://lists.ozlabs.org/pipermail/openbmc/2018-October/013696.html

Tested: Code update with field mode enabled, and ran Delete while
        host powered on, to check things still worked as expected.
