Fix performance and other misc issues with timeline view

[Quasar985]

Prerequisites

• Reviewed the checklist

• Reviewed feedback from the "Sonar Cloud" bot. Note that you have to wait
  for the "CI / Unit Tests") to complete first. Failed Unit tests can be
  debugged by adding the label "verbose logging" to the GitHub PR.

Description of the Change

Fixed performance issue with timeline view, which would previously cause the timeline view to take a long time to function for large graphs.
Other misc issues were fixed including:

• When nothing is selected, the range of the timeline view would change to be in the millions
• if range is 0, the timeline view can't scroll out or in anymore
• Transactions with no date time are now ignored, before they were treated as having a datetime of 0

Benefits

Performance boost and misc bug fixes to timeline view.

Possible Drawbacks

None

Verification Process

1. Open Consty
2. Create new graph
3. Experimental -> Build Graph -> Structured Graph Builder -> Click "Build"
4. After graph has finished building, Views -> Timeline
5. Observe Timeline View updates comparatively faster than on master branch (or older version of consty)
6. Select everything on the graph (Ctrl + A) and deselect everything (ESC) multiple times in quick succession
7. Observe Consty does not experience any out of memory issues

Applicable Issues

Some initial testing ...

The Timeline View does now load in a reasonable time, though it would be good to show a message that it is Loading in the graph, rather than saying No Active Graph.

After a few selects and zooms within the timeline view and directly on the graph, it gave me some out of memory errors:

java.lang.OutOfMemoryError: Java heap space
Dumping heap to C:\DEV\constellation\build\testuserdir\var\log\heapdump.hprof ...

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "Timer-0"
