pipenv --completion raises TemplateNotFound exception

[command-tab]

pipenv --completion used to output Bash completion commands. It now raises a TemplateNotFound exception:

Expected result

I expected pipenv --completion to output Bash completion snippet.

Actual result

It raises a TemplateNotFound exception.

Steps to replicate

1. Install pipenv under Python 3.6
2. Run pipenv --completion

[command-tab]

Of note: When I uninstall pipenv 2018.6.25 and install 2018.05.18, pipenv --completion works again. Thus it seems it was broken in the most recent release. I'm trying to find a specific commit...
