Variable name completion error after manual interruption and re-triggering

[VSteveHL]

Environment:

• OS: Debian 12 (64-bit)
• VS Code: Version 1.100.2
• Extension: Magic Scheme, version 0.0.5

Bug Description:

During the auto-completion of a variable, if the VSCode variable completion process is manually interrupted (using the Esc key), and then the auto-completion feature is invoked again (using the Ctrl+Space shortcut), the variable name completion will be incorrect.

Steps to Reproduce:

You can use the following code snippet to reproduce this issue:

(let ((qwe-asd-zxc 1) (foo_bar 2))
  (when qwe-asd-zxc))

1. Create a new file with the extension .sls.
2. Enter the code snippet above.
3. When typing the variable after when, manually interrupt the auto-completion process.
4. Then, use the shortcut keys to re-trigger code completion. This should trigger the bug.

Expected Behavior:

The variable name should be completed correctly.
