Fix generated bash completion for Bash 3 (OSX) (#520)

Browse Source 
* Make preamble functions unique to command

Prior to this commit the functions in the preamble had names that didn't
vary based on the command for which the bash completion was generated.

This meant that if you had two bash completions with differences in the
preamble functions then only the last loaded function would be
available.

This commit prefixes all of these functions with the name of the command
so that multiple cobra generated completion files won't clash.

* Fix function names in writeFlagHandler

The references to the `__handle_filename_extension_flag` and
`__handle_subdirs_in_dir_flag` functions in `writeFlagHandler` hadn't
been updated correctly in the previous commits.

* Pass cmd into writeFlagHandler

This commit passes the cmd pointer into the writeFlagHandler so that the
`__handle_filename_extension_flag` and `__handle_subdirs_in_dir_flag`
functions can have the `cmd.Name()` prefixed.

* Update Bash completion tests

Prefixes the tested `__handle_filename_extension_flag` and
`__handle_subdirs_in_dir_flag` functions with the command name.
