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 (Being more permissive to files changing under insta #380)
• If we skip, the only change between the two within cargo insta review is that the crate changes from prqlc to prql-compiler
