package manager does not find packages

[Noam-Dori]

This is a severe bug that causes the main component of the plugin, the package manager (class ROSPackageManager) to fail in either indexing or in loading the packages it finds.
Please report any instances you encounter this bug, what product you were using (for example CLion 2019.3.4), what version of the plugin you were using, and if possible, the steps you took to get the bug.

In future version of the plugin a tool to detect and report this bug will be added to help solve it.

Information so far:

• this bug only happens in CLion.
• restarting the IDE can temporarily solve the issue.
• This issue causes autocompletion for .msg files to fail for any message file outside the current package for both types of packages (compiled package like std_msgs, or packages in the workspace or a package path)

changing the package manager from project component to project service might have solved the bug, but I am not too sure.
