[Question][Bug] Infile paramater value wrong after updating from 1.6.14 to 2.0.7

[Willem-Nieuwoudt]

We had to upgrade django-pipeline from 1.6.14 to at least 2.0.7 since we are currently in the process of upgrading django to version 3.2. After we made the update, our static files were not behaving the same anymore (css not loading). After a few days of investigating I saw that the infile parameter that is passed into the compile_file function in the LessCompiler class were not the same as the value we usually got before we made the update.

Seems like the infile value comes from compile function on the Compiler class in the init file.

    def compile(self, paths, compiler_options={}, force=False):
        def _compile(input_path):
            for compiler in self.compilers:
                compiler = compiler(verbose=self.verbose, storage=self.storage)
                if compiler.match_file(input_path):
                    try:
                        infile = self.storage.path(input_path)
                    except NotImplementedError:
                        infile = finders.find(input_path)
                    project_infile = finders.find(input_path)
                    outfile = compiler.output_path(infile, compiler.output_extension)
                    outdated = compiler.is_outdated(project_infile, outfile)
                    compiler.compile_file(project_infile, outfile,
                                          outdated=outdated, force=force,
                                          **compiler_options)

                    return compiler.output_path(input_path, compiler.output_extension)
            else:
                return input_path

I see the infile value is never passed into the compile_file function. No matter what happens in the try except, another variable called project_infile is created underneath and passed to compile_file, which in our case has the wrong value. Infile has the correct value. On the older version that we used the project_infile didnt exist and the infile value was passed to compile_file. Thank you in advance.
