Fixes #768

The reproducible example is in the linked issue.

Issue:

The outlier package threw the following error when trying to add a card:

Warning in observe() :
  The card could not be added to the report. Have the outputs for the report been created yet? If not please try again when they are ready. Otherwise contact your application developer
Error : Can't subset columns that don't exist.
✖ Column `order` doesn't exist. 
 when evaluating qenv code:
ANL_OUTLIER_EXTENDED[ANL_OUTLIER_EXTENDED$is_outlier_selected, columns_index]

Solution:

removed order column as it cannot be in the ANL_OUTLIER_EXTENDED dataframe

setdiff(names(ANL_OUTLIER), c("is_outlier_selected", "order"))
