Pending snapshot in nested crate is double-counted

[max-sixty]

What happened?

We have a layout like:

prql-compiler
|- Cargo.toml
|- src
|- ...
|- prqlc
   |- Cargo.toml
   |- src
   |- ...

When there's a single pending snapshot inside prqlc:

• insta reports "2 pending snapshots"
• On cargo insta review, if the first is accepted or rejected, we get an "File not found" error when it attempts to find the file for the second time (#380)
• If we skip, the only change between the two within cargo insta review is that the crate changes from prqlc to prql-compiler
