This reverts commit 8ad25003.

Reason for revert:

Findit (https://goo.gl/kROfz5) identified CL at revision 828478 as the
culprit for flakes in the build cycles as shown on:
https://analysis.chromium.org/p/chromium/flake-portal/analysis/culprit?key=ag9zfmZpbmRpdC1mb3ItbWVyQwsSDEZsYWtlQ3VscHJpdCIxY2hyb21pdW0vOGFkMjUwMDNkZTgwODIxMjhjM2IzNDU2NWVhMjg4ZGM3OGZhODhkYgw

Sample Failed Build: https://ci.chromium.org/b/8863329295603494640

Sample Failed Step: mojo_unittests on (none) GPU on Mac on Mac-10.14.6

Sample Flaky Test: NodeChannelTest.MessagesCannotBeSmallerThanOldestVersion

Original change's description:
> Mojo: NodeChannel should require a minimum size when using multiple versions
> 
> When we added support for versioned message we accidentally introduced a
> behavior where messages can be shorter than expected. This is what the
> behavior should be to allow older messages to be received. However,
> we know the minimum size is the oldest message version. We should
> never be allowed to go smaller than that.
