Various fixes

Problem

• Annotation attachment is no longer working when there are annotations with pen pressure.
• The attached annotations are not properly sorted.
• Task selection is lost on reload in entities page
• Search reload is broken when a task is unselected leading to not allowing to clear the search right away

Solution

• Add missing function to pressure path prototype
• Fix sorting function before extracting annotations
• Retrieve entityMap at the right time to allow task selection
• Apply search from route only if no task is selected
