Script doesn't get injected if only one object in template

[kmitch95120]

While looking at another issue, I stumbled upon this one.

1. Create a new template called test.tosc
2. Create a button called 'button1'
3. Create a scripts folder
4. Create a file called button1.lua and put something in it.
5. Pass the template to the injector and you'll see '! name: button1 - 0 injected'
6. Add a second object of any type and save the template and you'll see '! name: button1 - 1 injected'

From this point on the injector will work as expected. if you delete the second object and save the template, the problem will return.
