Float ranges with units triggers dimensional incompatible error in Julia v0.7

[zsoerenm]

julia> (-2.0Hz:1.0Hz:2.0Hz) / 1.0Hz
ERROR: DimensionError:  and Hz are not dimensionally compatible.

In Julia v0.6 this works perfectly fine.
This does work in Julia v0.7 though:

julia> (-2Hz:1Hz:2Hz) / 1.0Hz
-2.0:1.0:2.0
