spacemacs/helm-M-x-fuzzy-matching error if no matches are in command history.

Description :octocat:

spacemacs/helm-M-x-fuzzy-matching error if no matches are in command history.

Reproduction guide :beetle:

• Start Emacs
• M-x
• Begin typing a command that is not in the command history
• If the command is an org-mode command, this bug does not seem to occur

Observed behaviour: :eyes: :broken_heart:

When running M-x and typing in a function name, once the string being entered diverges from something in the command history completions do not work, even though possible functions are listed under the "Emacs Commands" section, attempts to complete the string cease and the following error appears in the minibuffer:

Expected that no error would appear and instead a matching emacs command would be highlighted as a suggestion.

@ksafford Is this still an issue? I'm not able to reproduce it.
