Expected Behavior

LS starts and initializes the directory correctly.

Actual Behavior

LS failed to finish initialization due to Windows-style paths being interpreted incorrectly.

Steps to Reproduce

1. Open a folder in Sublime Text on Windows with the above config
2. Open file with the above config from that folder
3. Watch LS log

This appears to be related to the fact that the client (Sublime Text LSP in this case) sends a URI which has an extra (IMO meaningless) slash / on Windows:

file:///C:/Users/Radek%20Simko/tf-test

which then resolves to

\C:\Users\Radek Simko\tf-test

when we'd expect it to be resolved to

C:\Users\Radek Simko\tf-test

I will try to understand how does the third slash get added to the URI in case of Sublime Text and check if other popular clients behave the same way - then in theory we could just use a different prefix on Windows (file:///).

[radeksimko]

Confirmed the same behaviour (path with extra slash) being returned from NeoVim CoC plugin, IntelliJ, and the VSCode Extension.
