FIX: Chat memory is not cleared when opening new project #413

related to : Chat memory is not cleared when opening new project #413

Modification of FileListManager so each VirtualFiles and File observers are segregated by project in a Hashmap data structure with project.getLocationHash() as Map, consequently "project" become a argument for each calls

Previously ChatMessageContextUtil was calling a getFiles method on FileLIstManager at:

List<VirtualFile> files = FileListManager.getInstance().getFiles(); grabbing indistinctively files belonging to the collection of files in FileListManager (Lists)

Now FileListManager is handling files and observers to these files in a hashmap.

In term of test (reproducing @mydeveloperplanet use case):

• Add a file to the prompt context (errorHandler.java)
• ask a question 'tell me something about this file' (running /explain)
• The response explains the file

Then

• open a new project (in a new IntelliJ window)
• ask a question 'tell me something about this file' (give me opitmizations on ErrorHandler class)
• The response is about the file added in step 1 (from another project) --> the response in the screenshot show the LLM has not be informed of any file named ErrorHandler in the chat context
