[Bug]: Multistep experiments have different time steps at transitions comparing pybamm and liionpack

Describe the bug

https://github.com/pybamm-team/liionpack/blob/37ebc63803469fc709747da0249bfce2aa74a75c/tests/integration/test_1p1s.py#L40

This test fails as liionpack creates 21 time points and pybamm 22. The difference is around the transition where pybamm repeats the step at 10 s for the new experiment (ie includes a zero'th entry for cycle 2) and lp doesn't. Liionpack doesn't do any re-initialisation of solutions and fixes time steps at solve. This isn't ideal but it's not a major problem either and would eventually be fixed by merging solver routines into PyBaMM
