it was a bug that deferred_multi_app_lib.dart wasn't listed.

[Bill Hesse, 2015/03/05 10:13:29]

With dart2js and dart2dart, the lib is compiled into the output file, and does
not need to be compiled separately.  This is why it was working on dart2js
browser tests.  For compiler == 'none' tests, we will need to copy this to the
output directory.  So we will need to distinguish between scripts, with a main()
function, that will be run on the page, and library files that just need copied
if there is no compilation stage.  It should be safe to add this, but dart2js
will just fail, or do nothing, or produce bogus output, I think.  It doesn't
look like it's failing.
