PrimitiveObjectFormatter eagerly reads integer where double could be preferred.

[Mpdreamz]

A bug in PrimitiveObjectFormatter which is used when deserializing
object was eagerly reading doubles as integers. This was flagged in
failing yaml test reproduce:

./build.sh rest-spec-tests xpack -f analytics -t t_test.yml -s "heteroscedastic t-test"

Scrollbars now also collapse when running the yaml tests now that
ShellProgressbar properly scrolls children into view this got to be a
tad excessive
