Allocation Purger sets a SoftwareResult test_name.

If an allocation is purged and its owner is a SoftwareResult without a
test_name, this will call set_test_name on that SoftwareResult. This is
a work around to invalidate SoftwareResults that are backed by purged
allocations. Eventually SoftwareResults should support some sort of
status property.
replace pronoun to remove ambiguity
provide more information in unstartable note for genotype_microarray

Since CQID has added a new cause for why genotype_microarray might be
missing I tried to clarify the different possibilities.
