Boot panel in project properties alters NB actions when it shouldn't

[Alessandro Falappa]

In a project not run/debugged trough the spring-boot-maven-plugin (i.e with the default NB configuration for maven projects that uses the maven exec plugin) perform the following sequence of actions:

1. open the project properties dialog
2. set the project main class
3. select the Spring Boot panel
4. Press OK button

As a result the generated NB actions are inconsistent and some properties essential for the maven exec plugin are deleted.

The behaviour is correct with the following sequence instead:

1. open the project properties dialog
2. set the project main class
3. Press OK button
4. reopen the project properties dialog
5. select the Spring Boot panel
6. Press OK button
