E464: Ambiguous use of user-defined command when editing .tf file and open a file explorer

[cainiaocome]

Does this bug happen when you install plugin without vim-polyglot? No

Describe the bug: Vim errors E464: Ambiguous use of user-defined command when I use command :Te to open a new file explorer tab in Vim, while current opening file is a terraform configuration file. It seems only happen when editing .tf terraform configuration files.

To Reproduce:

1. Install vim-polyglot plugin with Vundle.
2. Open a terraform configuration file.
3. Use command :Te to open a file explorer tab.

I know it's too late, but if some one has the same problem type :Tex instead of :Te, Vim will be able to difference :Terraform command from :Texplorer.
