git-am: catch missing author date early.

This change made git-am more difficult to use.

I tend to check-in a fair number of patches that didn't come from an e-mail message. In the past, I slap a Subject: and a From: on the top of the commit message and off I go.

With this change git-am fails b/c I haven't also conjured up the time, when in the past it figured out what time it was for me.

thanks,

git-am: catch missing author date early.

Even though commit-tree would default to the current time if the incoming e-mail message somehow did not record the timestamp, it is safer to catch the breakage sooner.

Sorry, and thanks for the report.

Jens complained the same yesterday and the change was reverted.
