Have to save file before I can create a template

[Forceflow]

Don't know if this is intended behaviour or not, but I have to save a new file first, before your extension allows me to create a template from it.

Steps to reproduce:

• Create new file (untitled, don't save it)
• Type your template
• Without saving, right click on the text contents, and use "template from file"
• The extension asks for a template name
• Enter a name and press enter

Without any feedback, I would expect the template to be saved - my template folder however, remains empty.

VSCode 1.19.1, latest version of the extension.
