inconsistent text edits from completion

### How are you using the lua-language-server?

NeoVim

### Which OS are you using?

MacOS

### What is the issue affecting?

Completion

### Expected Behaviour

I'm writing a completion engine for neovim which uses lsp to get completions among other things
I'm in the root directory of my plugin "neocomplete"
now I get completions for `require"neo|`, want to be able to select "neocomplete" and correctly get this completed to `require"neocomplete`

### Actual Behaviour

`require"neo|` -> selecting "neocomplete" -> `require"neocompleteo`
`require"neo|"` -> selecting "neocomplete" -> `require"neocomplete"`
I checked out the completion items returned by the server and it seems it provides a different `end` range for the text edit in these cases even though in both cases it should simply replace `neo` with `neocomplete`

### Reproduction steps

See above

### Additional Notes

Tell me if I can give you any additional information from the completion results

### Log File

_No response_

Reproduce the two completion cases in NeoVim using the `require"neo|` and `require"neo|"` examples, then inspect the completion items and their LSP text-edit ranges. The fix is complete when selecting `neocomplete` replaces `neo` correctly in both forms without leaving an extra character.
