remove deprecated throw declarations

[BenjaminW3]

Dynamic exception declarations with throw(...) are deprecated.

In C++11 destructors will implicitly be marked noexcept(true).
Therefore the destructor of TransactionManager will have to be declared noexcept(false) then.

I am not sure but that looks like mixing c++03 and c++11. Are Dynamic exception declarations with throw(...) deprecated in c++03 ?

[BenjaminW3]

You are right. Nevertheless I propose to remove them.
In previous commits other such declarations have already been removed and these are the last occurences in libPMacc.
The working paper that proposed deprecating them gives some reasons to not use them:

Run-time checking: C++ exception specifications are checked at runtime rather than at compile time, so they offer no programmer guarantees that all exceptions have been handled. The run-time failure mode (calling std::unexpected()) does not lend itself to recovery.
Run-time overhead: Run-time checking requires the compiler to produce additional code that also hampers optimizations.
