CodeMaid Options not accessible when opening a file without a solution

[codecadwallader]

Environment

• Visual Studio version: 2015 Professional
• CodeMaid version: 10.0.75
• Code language: JavaScript

Description

If you open a single JavaScript file within Visual Studio, there won't really be a solution associated with it and the CodeMaid Options dialog is not accessible. There is an error dialog, and I suspect it is failing when it tries to resolve the path for the pseudo-solution that Visual Studio creates when there is no real solution open.

Steps to recreate

1. Open Visual Studio
2. File->Open and select an individual JavaScript file
3. Select CodeMaid->Options

Current behavior

An error dialog is shown stating "The path is not of a legal form."

Expected behavior

The options dialog should be shown as normal.
