ESR91: Basic Authentication doesn't work with ESR91

[rainemak]

Visiting a site requesting basic auth credentials doesn't work on ESR91. With ESR78 a Silica credential dialog is shown, but with ESR91 "authorization required" HTTP status page is immediately shown.

Based on quick look, it looks that a wrong nsILoginManagerPrompter implementation is getting loaded and hitting then Prompter.jsm that we do not have implemented/used. We have similarly cleared Prompter creation from DownloadPrompter.

I'd think that there are changes in the idls implemented by embedlite-components LoginManagerPrompter that we are missing. Thus, a wrong implementation is loaded.
