Fix issues found by JET.jl

[JoshuaLampert]

In DispersiveShallowWater.jl, we get errors from JET.jl v0.11, which stem from @trixi-timeit in TrixiBase.jl, see NumericalMathematics/DispersiveShallowWater.jl#248 (comment): local variable accumulated_data may be undefined: accumulated_data::TimerOutputs.TimeData. This PR puts accumulated_data in the second if block to fix this. I verified locally that this fixes the issue.

Failing tests are due to world age issues with trixi_include introduced in Julia v1.12 and already appeared in https://github.com/trixi-framework/TrixiBase.jl/actions/runs/18938535502/job/54071313304 (which was the first test run, where Julia v1 was resolved to v1.12). Edit: Should be fixed with #58.
