"successful" release:perform with dryRun=true should not invoke release:clean

I recently upgraded maven-release-plugin version to 2.4.2 from 2.0

I observed a change in the behaviour of release:perform together with dryRun (on a side-note, in 2.0 dryRun user property did not seem to have an effect on release:perform)

basically:

1. dryRun=true release:prepare

2. dryRun=false release:prepare: generate tag+release info

3. dryRun=true (due to it being considered in 2.4.2) release:perform: no deployment into repository, BUT release:clean removes release info

4. dryRun=false release:perform: fails, lacks release info

I know I should not do step #3, but I recommend not to execute release:clean after a "successful" release:perform with dryRun=true
