Test check_tidy_omic edge cases

Code
  check_tidy_omic(double_data_tidy, fast_check = FALSE)
Error <simpleError>
  100 measurements were present multiple times with
       the same feature and sample primary keys

       For example:

       feature = 1 ; sample = 1
  feature = 1 ; sample = 2
  feature = 1 ; sample = 3
  feature = 1 ; sample = 4
  feature = 1 ; sample = 5
  feature = 1 ; sample = 6
  feature = 1 ; sample = 7
  feature = 1 ; sample = 8
  feature = 1 ; sample = 9
  feature = 1 ; sample = 10

Code
  create_tidy_omic(degenerate_attributes %>% select(-degen_sample_var),
  feature_pk = "features", sample_pk = "samples", feature_var = "degen_feature_var",
  verbose = FALSE)
Error <simpleError>
  "degen_feature_var" was duplicated for 10 features
  this variable should not be a feature attribute.

Code
  create_tidy_omic(degenerate_attributes %>% select(-degen_feature_var),
  feature_pk = "features", sample_pk = "samples", sample_var = "degen_sample_var",
  verbose = FALSE)
Error <simpleError>
  "degen_sample_var" was duplicated for 10 features
  this variable should not be a feature attribute.

Factor primary keys are preserved when converting from a tidy to a triple

Code
  create_tidy_omic(three_col_df_fct, feature_pk = "features", sample_pk = "samples",
    sample_vars = "measurement", feature_vars = "measurement", verbose = FALSE)
Error <rlang_error>
  measurement were assigned to multiple classes of variables each variable should only belong to one class

Test that get_tomic_table() can retrieve various tables

Code
  infer_tomic_table_type(simple_tidy, samples_df %>% rename(fake_samples = samples))
Error <simpleError>
  based on the "tomic" primary keys, tomic_table doesn't appear to
         be features, samples or measurements
