Auto merge of #6188 - bundler:indirect/fix-6072, r=indirect

Stop overriding specs during double-checks

This fixes my test-case reproduction of #6072. I’m pretty sure it’s because
the double-check was overriding the locally installed index specs with
specs fetched from the RubyGems API, causing Bundler to conclude that the
gems aren’t installed, even though they are.

@deivid-rodriguez @y-yagi can you verify that this patch fixes the issues with `inline` that you were seeing?
