fixes return passing output from command through jxmlease in junos_command (#5044)

The return string from the commands was not being passed through the
jxmlease library and therefore being returned as a string instead of a
json data structure.  This also adds back the missing xml key in the
return that includes the raw xml string.

fixes #5001
