Fail on second attained goal that uses reactor

[Alexei Barantsev <ba...@kazbek.ispras.ru>]

Let's imagine a simple project that have a subproject.

Parent's maven.xml (see below) defines two goals (run1 and run2) that
use reactor to do something with the subproject, and two goals (run12
and run21) that attain goals run1 and run2 in different order.

Goals run1 and run2 works as expected whereas goals run12 and run21 do
not - they execute first attained goal and then fail on second.

What's the matter?
