Use double quotes in error message (#2112)

On Windows, double quotes are required, because single quotes get served to youtube-dl. (Yes, cmd.exe is crazy like that).
On other system, both double and single quotes are fine, unless the string contains a dollar sign (then you need single quotes).
Since virtually no URLs contain dollar signs, double quotes should do.
