the plugin doesn't work properly with the very first opened/created file every time st2 restarts

repro:

1. quit ST2 WITHOUT any ts file opening
2. open ST2 and create a new file, save it as a.ts, and write some code, you'll find it's laggy, and you can not build it with Cmd + B (nothing with the plugin works, actually)
3. create another file saved as b.ts, it's working properly.
4. keep b.ts as the current active file, and quit ST2 with Cmd + Q
5. reopen ST2 and you'll find the issues come with b.ts, but a.ts works properly.
6. close b.ts and reopen it, you'll find it working properly.

No source file, test, or entry point is named. Start by reproducing the restart sequence in Sublime Text 2 with the listed plugin and system versions, comparing the first restored file with a newly reopened file. Done means the first opened or created TypeScript file behaves like the second file, including building with Cmd+B and normal plugin features.
