RemoteSecuritySettings.init throws error in console

Noticed in 13.0 alpha and dev build.

Some time after startup, I get an error in the console

TypeError: this.client is undefined     RemoteSecuritySettings.sys.mjs:538:7

Basically, RemoteSecuritySettings.init, which is triggered in BrowserGlue.sys.mjs throws because CRLiteFilters was not initialized. I think this is a side effect of our patch "Bug 31740: Remove some unnecessary RemoteSettings instances".

/cc @pierov or @ma1 you might know what's best to do here.
