Setting `sparse-profile: None` on a toolchain task produces an error

According to  a toolchain task should be able to set `sparse-profile: None` to not use a sparse profile. However when actually trying to do so, it produces an error: [vcs 2018-11-19T20:14:39.356Z] abort: sparse profile build/sparse-profiles/None does not exist at revision 28421835d90c40a8af63ff8d01591e8110f07bac  https://searchfox.org/mozilla-central/rev/b03a62c3c82316e733a3b09622c1cb7e59f64cc3/taskcluster/taskgraph/transforms/job/toolchain.py#54
Also note the only toolchain that tries to take advantage of this actually sets it to `null` instead of `None`: https://searchfox.org/mozilla-central/rev/b03a62c3c82316e733a3b09622c1cb7e59f64cc3/taskcluster/ci/toolchain/linux.yml#473
That abort message implies that the string "None" is making its way through the config. I'm guessing YAML doesn't recognize `None` as an alias for "undefined" and that `null` is needed instead? A quick fix for this would be for taskgraph to verify the sparse profile file as specified in the config exists in the current revision.

This is because yaml and python spell things differently as :gps suggested. YAML spells `None` as `null`. This could be better documentated, but is working as expected.

This would definitely be useful.
