Changes to Formatter profiles don‘t take effect in real time

[CsCherrYY]

Steps to reproduce:

1. Open a new Java project, use Java: Open Java Formatter Settings and choose the default profile
2. Change the setting org.eclipse.jdt.core.formatter.blank_lines_before_imports in the xml to 5
3. Command palette: Format Document, you'll find that there is still one line before imports
4. Reload window
5. Command palette: Format Document again, you'll find that there is five lines before imports now

It seems that the issue occurs here: https://github.com/eclipse/eclipse.jdt.ls/blob/6bc7aef77e9497cef27bc4e3b9b50ccdb8ea6170/org.eclipse.jdt.ls.core/src/org/eclipse/jdt/ls/core/internal/managers/StandardProjectsManager.java#L192-L200

In windows system, the condition check in line 196 will be always false since the drive letters between the two URIs are not the same. One of them is in uppercase while the other is in lowercase. This dismisses the rest configure process.
