CircularAperture's report `nan` instFlux, `inf` instFluxErr

      Description

      The CircularAperture algorithm appears to have an edge case where the instFlux value is `nan` but the instFluxErr is `inf` rather than both values being `nan`.

       

      When `flag_apertureTruncated` is set, both values are `nan` however, when this value is not set and the instFlux is `nan`, instfFluxErr is `inf`. And set of example values is shown below. The bug was found while running ap_pipe on the HiTS2015 dataset.

      base_CircularApertureFlux_25_0_instFlux: nan
      base_CircularApertureFlux_25_0_instFluxErr: inf
      base_CircularApertureFlux_25_0_flag: 0
      base_CircularApertureFlux_25_0_flag_apertureTruncated: 0
      base_CircularApertureFlux_35_0_instFlux: nan
      base_CircularApertureFlux_35_0_instFluxErr: nan
      base_CircularApertureFlux_35_0_flag: 1
      base_CircularApertureFlux_35_0_flag_apertureTruncated: 1
