`compute_and_write_tracks_info()` doesn't construct appropriate `Filters` tables.

[jwaiton]

compute_and_write_tracks_info() is the backbone of each topological city (isaura and esmeralda).

It currently creates two filter tables:

• hits_select: a table that displays if an event has any hits or not
• topology_select: a table that displays if an event has any topological information

These two tables (within my testing) are always empty, although I'm unsure exactly why this is.
