Extra simulations for Parameter Sensitivity Analysis (PSA) plots

[stevechoy]

Whenever a new parameter is selected from the drop-down list, the PSA simulations are conducted twice (the plot refreshes twice).
The final plot shows the correct parameter values, while the intermediate plot shows the previous parameter's values (e.g. if previous parameter was CL and its associated values was 1, 2, 3, and the new parameter is V, the intermediate plot first shows 1, 2, 3, before updating to the final values of 10, 20, 30).

This behavior is now corrected by introducing a reactive dependency for new_sim_min_model_1, new_sim_mid_model_1, new_sim_max_model_1 to input$param_min_id_model_1, input$param_mid_id_model_1, and input$param_max_id_model_1, respectively, i.e. adding %>% bindEvent(input$param_min_id_model_1) at the end of the reactive. (ditto for model 2)

This is fixed for next release (v0.2.9).

Turns out it is not enough to just introduce a single reactive dependency as other arguments such as sampling_options() would not be updated when changed. A deeper look into the reactive dependency is required to fix this.
