Florian Müllner 636ab4b0e9 extensions-tool: Split out get_extension_property() helper
For the prefs command, we first fetch the extension info to check
whether the extension exists and actually has preferences. This
pattern can be useful for other commands and properties, so split
out a generic helper function.
