When it is forced build, the status icon of the project doesn't change if there are other projects waiting to be processed in build-prepare-queue. Users get confused that nothing happened especially if the project that precedes it is very big (hence taking too long to finish). We can change the status icon of the project to "in queue" as an indicator that it is already inserted in build-prepare-queue.
1. add a small project
2. add a big project
3. build the big project and then immediately build the small project.
notice the status icons of the small project, it will only be updated once the big project has finished processing in the build-prepare stage.
