"symflower unit-tests" timeout error differs between Linux and Windows

[ruiAzevedo19]

The error messages from the "symflower unit-tests" timeout differ on Linux and Windows

• Linux: signal: killed
• Windows: it has a weird behavior, sometimes the error is context.DeadlineExceeded other times exit status 1

Tests for this can be found in model/symflower/symflower_test.go:TestModelGenerateTestsForFile

Workaround: #277

TODO

• Investigate why the errors differ between Linux/Windows
• Investigate why there are two possible error messages on Windows

Windows and the rest of the world are often different. so i think this is fine. And already implemented with the PR. so closing.
