Avoid shared reference in ElectrodeSource.efields to fix mulitple elecric fields stimulus on mulitple cells (#537)

## Context
Fixes #538 
The current `ElectrodeSource.efields` for each cell is instantiated with
a shared reference. At the time of `__iadd__`, `ElectrodeSource.efields`
gets extended with the e-fields from the 2nd spatially_uniform_e_field
input. If it is shared reference, `ElectrodeSource.efields` of cell A
gets extended at the time of `__iadd__` for cell B, cell C ... etc.
That's wrong.
This PR makes `ElectrodeSource.efields` to hold an independent copy.


## Testing
1: `tests/unit/test_multiple_extracellular_stimuli.py`: change the input
target to the same muiltiple cells that could reveal the issue without the fix.
