NA values propagate from binary precision()

Code
  out <- precision_vec(truth, estimate)
Condition
  Warning:
  While computing binary `precision()`, no predicted events were detected (i.e. `true_positive + false_positive = 0`).
  Precision is undefined in this case, and `NA` will be returned.
  Note that 2 true event(s) actually occurred for the problematic event level, a
Code

NA values propagate from binary recall()

Code
  out <- recall_vec(truth, estimate)
Condition
  Warning:
  While computing binary `recall()`, no true events were detected (i.e. `true_positive + false_negative = 0`).
  Recall is undefined in this case, and `NA` will be returned.

  Warning:
  While computing binary `recall()`, no true events were detected (i.e. `true_positive + false_negative = 0`).

  Warning:
  While computing binary `precision()`, no predicted events were detected (i.e. `true_positive + false_positive = 0`).

Multiclass f_meas() returns averaged value with NAs removed + a warning when recall is undefined (tp + fn = 0) (#98)

Code
  out <- f_meas_vec(truth, estimate)
Condition
  Warning:
  While computing multiclass `recall()`, some levels had no true events (i.e. `true_positive + false_negative = 0`).
  Recall is undefined in this case, and those levels will be removed from the averaged result.
  Note that the following number of predicted events actually occurred for each problematic event level:
  'c': 1
