bug#50289: [PATCH] import: go: Fix import when import path redirects.

[Ludovic Courtès]

Hi,

Sarah Morgensen <iskarian@mgsn.dev> skribis:

> As reported by Attila on IRC, the Go importer currently chokes when the
> import path URL redirects, for example with "github.com/prometheus/tsdb".

> This is due to my modification to 'fetch-module-meta-data' to handle multiple
> package's meta tags on one page [0].  It selects the meta based on whether its
> import prefix matches the URL we requested.  This breaks when the URL
> redirects but the import path is not changed (I did not realize that this
> was valid... go figure).  This patch fixes that by falling back to the first
> meta if none match.
