Changes to ${revision} in profiles do not propagate to the final project version

[g667]

Affected version

4.0.0-rc-4

Expected behavior

When the POM references ${revision}, the resolved value of ${revision} should determine the project version, including cases where ${revision} is set or overridden in a profile.

Observed behavior

${revision} is resolved correctly, but its value is not applied to the final project version.

Steps to reproduce

Execute the provided pom.xml file

Case 1: No profile activated

Expected final version includes "+dev"

$ mvn clean
...
[INFO] Building m4-demo-revision 0.2.0+dev
...
baseVersion    : 0.2.0
revision       : 0.2.0+dev
project.version: 0.2.0+dev
version        : 0.2.0+dev

Case 2: Release profile activated

Expected final version is only baseVersion without "+dev"

$ mvn clean -PreleaseBuild
...
[INFO] Building m4-demo-revision 0.2.0+dev
...
baseVersion    : 0.2.0
revision       : 0.2.0
project.version: 0.2.0+dev
version        : 0.2.0+dev

Case 3: Manipulation profile activated (setting ${version} directly)

${version} is set directly and the change is applied, but it still does not affect the final project version

$ mvn clean -PmanipulateVersion
...
[INFO] Building m4-demo-revision 0.2.0+dev
...
baseVersion    : 0.2.0
revision       : 0.2.0+dev
project.version: 0.2.0+dev
version        : 0.2.0

Note: This is not the intended use case, but maybe it is a hint what's going on here, since it is possible to set the shorthand property ${version}, which then differs from ${project.version}.
