applySnippetWorkspaceEdit selects wrong token

[TimoFreiberg]

Tracking for the bug described in #252 by @oblitum
Opening a bug here because I don't see this behaviour in the VS Code plugin.

When triggering the "Add function" codeaction in this file without an empty line at the end:

fn main() {
    foo<|>();
}

The following is generated:

fn main() {
    println!("Hello, world!");
    foo();
}
fn foo() {
    todo!()
[}]

with the closing brace of the generated function being selected (highlighted with [] brackets).

When triggering the codeaction in the same file with an empty line at the end (which rustfmt removes for me 😅 ), the todo!() is correctly selected

The logic of applySnippetWorkspaceEdit looks equivalent to the one in the VS code plugin (compare coc-rust-analyzer with VS Code, so maybe this is a coc.nvim bug?
