Fullpath contains double slash before filename

[chinise]

When running command like this in lir buffer

:lua print(require"lir".get_context():current().fullpath)

the resulting path looks like: /home/my_user//test.txt on wsl C:\Users\my_user\\test.txt on windows

using:

• lir: commit 969e95b
• nvim v0.9.4
• both on windows and wsl
