invalid use of Lazy<GitVersionContext>, #2933 fix doesn't work actualy

Fixes #2927

Related Issue

#2927

Motivation and Context

Invalid use of Lazy leads the fix of #2933 doesn't work properly. this.versionContext.Value will always be null. This problem was bypassed by way of early access in unit test.
if replace

        bool isCurrentCommitTagged = this.versionContext.IsValueCreated &&
            this.versionContext.Value.IsCurrentCommitTagged;

with
bool isCurrentCommitTagged = context.IsCurrentCommitTagged;,
will cause many other unit tests failed.
So I have to move the if statement into the NormalizeGitDirectory method.

How Has This Been Tested?

Tested the reproduce case in #2927.
all unit tests passed
