    Fix invalid home test
    
    If a user has set environment variable GNC_DATA_HOME
    to a valid directory (containing real gnucash metadata)
    the test would fail. It expects to follow the code path
    to set up a gnucash data home directory in the temporary
    directory, but the directory pointed to in GNC_DATA_HOME
    is used instead.
    Fix this by also setting environment variable GNC_DATA_HOME
    to something invalid during the test.
