GenericExecutionStats has no field counters when using solve_problems

[geoffroyleconte]

Since the counters have been removed from the GenericExecutionStats type I have this error message when using solve_problems

┌ Error: caught exception
│   e = type GenericExecutionStats has no field counters

This does not seem to be shown in the breakage tests so I open an issue just in case.

I got something similar

┌ Warning: failed to run `@example` block in src/benchmark.md:124-126
│ ```@example ex1

when stats is the result of bmark_solvers in DCISolver.jl https://github.com/JuliaSmoothOptimizers/DCISolver.jl/runs/7733825128?check_suite_focus=true
