Investigate root cause of #72

This is pretty low priority, but it would help me sleep at night :)

It is pretty simple to reproduce #72.

• Do everything in VS Code
• Create a .ts file, write some code, save it
• Then copy the file in VS Code explorer and paste it (it will create file named: Myfile copy.ts)
• ts2gd will show message: TS can't find source file /home/adam/Documents/git/adamuso/test-project/scripts/src/BaseNode copy.ts after waiting 1 second. Try saving your TypeScript file again.
• DO NOT save it again like says in the message
• Rename the file to something else (now the exception happens)
