This can't do the "correct" thing, and check if the method is defined, because `FnCtxt::lookup_method` isn't accessible in Clippy. To work around this problem, we convert method calls to FQP syntax if the user specifies a full path as a replacement. If they specify only a name, then we only replace the name. Since clippy.toml resolves paths from the top level of the crate, this is basically guaranteed to produce a correct result, if we ignore method call adjustments like autoderef.
