scraper: fix SLR trans scene cover images (xbapps#1641)

* Update slrstudios.go

* Incorporates the changes from xbapps#1624 as new fallback for failure to retrieve cover image using API
* Fixes trans covers, they are broken at the moment for the same reason that necessitated xbapps#1624 but required a different fix

* Update slrstudios.go

Forgot to import `net/url`, gofmt

* URL decoding was unnecessary. String replacement.

* Unrelated: (temporary) gitpod environment fix for achrinza/node-ipc#59
