Added cursor position check before running prompt history trigger

[dogusata]

Problem

• When using the up and down arrow keys to grab previous prompts like in a terminal, it is not possible to navigate through the text anymore. It should only trigger the historical previous/next prompt actions when on the first and last lines
• Cursor jumps to text end after up and down arrow actions even if there is no previous prompt available.

Solution

• Added current cursor line check before triggering historical prompt calls.
• Fixed unnecessary cleanup which causes a cursor jump to the end.

Tests

• I have tested this change on VSCode
• I have tested this change on JetBrains

I would suggest adding some test cases to the ui tests to check for some cases:

• Going up and down in a multiline prompt
• Going up when the prompt input area is empty
• Test case where the cursor is initially in the first line and then window size is shrunk down and the cursor moves to the next line
