fix(livereload): wrong usage of reject, meant resolve. (#167)

* fix(wkwebview): Images not loading in Ionic WKWebView

* fix(livereload): Images not loading

When running in an emulator or in a device with the flag --livereload images were not showing.

* lint(livereload): Updated for ihadeed comments

* fix(livereload): Using reject instead of resolve

Reject caused an error and did not return the URL. Fixed this resolving and returning the image URL back to the promise.
