App.import should throw exception when someone passes a bad type

<strangelooper> rwjblue it doesn't look like the code is checking for anything other than if(options.type === 'vendor')  the else statement stuffs your asset into legacyTestFilesToAppend
<rwjblue> yes, I know
<rwjblue> I'm saying it should
<strangelooper> oh, want me to make a pr with `else if( options.type === 'test' ){`'  ?
<strangelooper> :-)
<rwjblue> yes, then error in the final `else` case
<strangelooper> cool
