In SCTK shiny app, issue with refreshing parameters entered by the user

[apeleraux]

The advantage of a shiny app is to enable users to follow a trial and error approach. They select some parameters and values, run a calculation and often want to modify the parameters and values and run the calculation again. However, it appears that refreshing parameters is not working properly in the SCTK shiny app.
For example, in the QC & filtering tab :

• set some filtering criteria,
• filter and see how many cells are left,
• modify the filtering criteria by removing a filter or even clearing all filters
• filter again
  => the number of cells passing filter stays the same.
  From that point on, the user can no longer modify threshold values defined for each criterion:
• remove a filtering criterion
• add the same cell filtering criterion again
  =>the same threshold is automatically selected, the user cannot enter a new threshold value.
  Similar refreshing issues also occur in other tabs.

I forgot to mention that I am using SCTK v2.6.0.
