Fixes breaking changes from #3624 (#4072)

* removes breaking change from electrode diffusivity -> particle diffusivity

* Add conditional entry for base_solver inputs recreation

* fix: incorrect depreciated parameter translation, moves conversion to ParameterValues staticmethod

Fixes an incorrect conversion of electrode diffusivity to particle diffusivity,
Updates the corresponding test to ensure FuzzyDict.__getitem__ functions correctly,
Adds conversion and checks to BaseSolver inputs object,

* Add changelog entry

 ## Bug Fixes
 
+- Fixes the breaking changes caused by [#3624](https://github.com/pybamm-team/PyBaMM/pull/3624), specifically enables the deprecated parameter `electrode diffusivity` to be used by `ParameterValues.update({name:value})` and `Solver.solve(inputs={name:value})`. Fixes parameter translation from old name to new name, with corrected tests. ([#4072](https://github.com/pybamm-team/PyBaMM/pull/4072)
 - Set the `remove_independent_variables_from_rhs` to `False` by default, and moved the option from `Discretisation.process_model` to `Discretisation.__init__`. This fixes a bug related to the discharge capacity, but may make the simulation slower in some cases. To set the option to `True`, use `Simulation(..., discretisation_kwargs={"remove_independent_variables_from_rhs": True})`. ([#4020](https://github.com/pybamm-team/PyBaMM/pull/4020))
 - Fixed a bug where independent variables were removed from models even if they appeared in events ([#4019](https://github.com/pybamm-team/PyBaMM/pull/4019))
 - Fix bug with upwind and downwind schemes producing the wrong discretised system ([#3979](https://github.com/pybamm-team/PyBaMM/pull/3979))
