UnitfulExt not working for logarithmic units

[ykonter]

UnitfulExt currently does not work for logarithmic units.
Example:

using Plots
using Unitful:m, dB, dBm
plot( (1:10)m) # works
plot( (1:10)dB ) # does not work, produces error
plot( (1:10)dBm ) # does not work, produces error

The error reads

ERROR: MethodError: no method matching isinf(::Gain{Unitful.LogInfo{:Decibel, 10, 10}, :?, Int64})

@ykonter wrote a PR on UnitfulRecipes to fix this partially about a year ago. I don't quite remember where that landed, it's possible I got caught up in completionism and forgot to merge the parts that worked.

I can see if I can find some time to look it through this weekend.
