Attribute error on startup in objects.py resolve_includes

[AnsonKoch]

Describe the bug
When starting fortls from VS Code, within particular arrangements of Fortran source code, fortls crashes with an attribute error. This is traced back to objects.py, in the resolve_includes method, where it is caused by parent_scope being None.

To Reproduce
Unsure as to what exactly it is about my source that causes this. Unfortunately, I am unable to share my code here.

Setup information (please complete the following information):

• OS: windows 10
• Python Version 3.12
• fortls Version 2.13.0
• Code editor used vs code
• the Fortran extension for the code editor and its version Modern Fortran 3.2.0

Additional context
I edited objects.py by adding an if statement to bypass the problem lines, by checking if parent_scope is not None. This seems to have fixed the problem, but I have not reviewed the fortls code to know if my modification will produce other errors down the road.

Can you share the diff of fortls object.py file? Also it would be good if you could form a MWE otherwise it will be hard to replicate

Here's the diff:

The minimum working example will take a while to generate, as I'll need to track down what causes the error, but I'll post it if I figure it out.
