"Haskell: Stack Build" starts with `cd "'1.4.1.2'"`, a non-existent directory

• Windows 10 Insider Preview (build 17134.1 (latest as of writing))
• Visual Studio Code 1.22.2
• Haskelly 0.5.2

Here's what shows up in the integrated terminal in VS Code after I run Haskell: Stack Build:

PS C:\Users\me\Projects\Dust> cd "'1.4.1.2'"
cd : Cannot find path 'C:\Users\me\Projects\Dust\'1.4.1.2'' because it does not exist.

(Note also the color codes, I don't think they should be there but that looks like an upstream issue, whether in VS Code or Windows itself.)

It's because of the code in workDir.ts here

const re = /.*path:\s*(.*?)\s*?\n/

This regex now matches a stack query result which contains the package named filepath of version 1.4.1.2. I tested locally with changing the regex to have a required whitespace before the path part like this

const re = /.*\spath:\s*(.*?)\s*?\n/

and it fixed the problem for me.

This bug has been fixed in version 0.5.3 thanks to MR #77.
