Failure when using source replacement

[cyqsimon]

When a source replacement is specified for crates.io in ~/.cargo/config.toml, updating using cargo install-update -a will fail:

Updating PKG
error: registry index was not found in any configuration: `SOURCE`

Steps to reproduce

1. Append the following to ~/.cargo/config.toml:

[source.my-replacement-source]
registry = "https://github.com/jhnc-oss/crates.io-index.git"
[source.crates-io]
replace-with = "my-replacement-source"

You can use any valid registry; I just picked the most recent GitHub fork of https://github.com/rust-lang/crates.io-index.

2. Run cargo install [email protected] to verify the registry setting. Again, you can use any valid binary crate.
3. Run cargo install-update -l to verify that fd-find has an update.
4. Run cargo install-update -a and observe the failure.
5. Don't forget to reset ~/.cargo/config.toml after testing.

Dupe of #185, documented in https://github.com/nabijaczleweli/cargo-update#source-replacement-vs-custom-registries – you need an index key with the same value as registry, this was broken by cargo 2019-09-10.
