Feature/axis name generation handle missing info

[dedeibel]

I am suggesting this change since I noticed two "problems" with the axis label handling.

1. If there is no axis name specified there would be a space character before the unit part e.g.: _[V] (Space replaced by _ in the example)
2. If there was no unit specified an empty set of brackets would be used: []

• (Often seen when people don't set a unit - not so pretty in IMO)

The change would result in the following behaviour (taken from the tests):

Axis name, unit, scale

"axis name", "axis unit", 1.    → "axis name [axis unit]"
"DeviceA", "V", 1.              → "DeviceA [V]"
"DeviceA", "V", 0.001           → "DeviceA [mV]"
"axis name", null, 1.           → "axis name"
"", "V", 1.                     → "[V]"
null, "V", 1.                   → "[V]"
"", "", 1.                      → ""
null, null, 1.                  → null

In our code we extended DefaultNumericAxis because of this. With the changes this would not be necessary.

Please consider the above suggestion for integration.
