Optim.jl Start in interior of variable bounds

As highlighted in https://github.com/JuliaNLSolvers/Optim.jl/issues/1071, most tests were failing because the starting point was infeasible. With this PR, most are now passing. The remaining ones to investigate are:

test_nonlinear_expression_hs071 : this one gives an infeasible solution, not sure if it's due to the fact that the starting values does not satisfy the constraints, no warning is thrown though.
test_nonlinear_expression_hs071_epigraph : the variables are in the interior of the bounds but some of the constraints are not satisfied hence the warning is thrown. Then it converges to an incorrect solution
test_objective_FEASIBILITY_SENSE_clears_objective : this one seems it may be a bug in the MOI wrapper, let me investigate first
