Get the "first_attr_start_pos" from a samplelist instead of from each individual sample, because it was previously causing problems when only some samples had an N

* wqflask/base/webqtlCaseData.py - Removed code getting first_attr_start_pos
* wqflask/wqflask/show_trait/SampleList.py - Added code getting first_attr_start_pos and assigning it to all samples + removing one unnecessary sort
* wqflask/wqflask/static/new/javascript/initialize_show_trait_tables.js - Fixed issue that was causing the N column to not be displayed
