crashes with ValueError when the import to remove appears twice

[Jasha10]

Description

autoimport sometimes throws ValueError when the import to remove appears twice

Steps to reproduce

Create the following python file:

# tmp.py
import my_module.m
from my_module import _tm

Invoke autoimport:

 $ autoimport tmp.py
Traceback (most recent call last):
  File "/home/rig1/miniconda3/envs/utils/bin/autoimport", line 8, in <module>
    sys.exit(cli())
  File "/home/rig1/miniconda3/envs/utils/lib/python3.10/site-packages/click/core.py", line 1130, in __call__
    return self.main(*args, **kwargs)

    rv = self.invoke(ctx)

    fixed_code = services.fix_files(flattened_files, config)
  File "/home/rig1/miniconda3/envs/utils/lib/python3.10/site-packages/autoimport/services.py", line 29, in fix_files
    fixed_source = fix_code(source, config)
  File "/home/rig1/miniconda3/envs/utils/lib/python3.10/site-packages/autoimport/services.py", line 73, in fix_code
    return SourceCode(original_source_code, config=config).fix()
  File "/home/rig1/miniconda3/envs/utils/lib/python3.10/site-packages/autoimport/model.py", line 68, in fix
    self._fix_flake_import_errors()
  File "/home/rig1/miniconda3/envs/utils/lib/python3.10/site-packages/autoimport/model.py", line 288, in _fix_flake_import_errors
    self._remove_unused_imports(import_name)
  File "/home/rig1/miniconda3/envs/utils/lib/python3.10/site-packages/autoimport/model.py", line 454, in _remove_unused_imports
    imports.remove(object_name)
ValueError: list.remove(x): x not in list

Strangely, this bug seems dependent on the exact names of the imports. For example, if I do from my_module import _t instead of from my_module import _tm, no ValueError occurs.

Environment

 $ python -c "import autoimport.version; print(autoimport.version.version_info())"

Weird indeed, only the combination you showed make the error raise. Any other combination of the elements works.

I'll try to take a look whenever I can, as always, if you can jump forward and do a PR, I'll appreciate it a lot :)
