Revert "Item9693: Set a proper alpha version id."

This reverts commit 0f1a41d2cb40b2eacc1345bc7d4ca3f16d2e218d.

Per perl version strings,  the alpha release before 1.2.0 would be
1.1.9999_999 or similar, so that it is numerically less that 1.2.0 but
higher than any 1.1.x release.

However the unit tests check for release < 1.2 to detect 1.1.x code, so
using the "proper" alpha release breaks all the release dependent unit
tests.

Reverting for now.
