fix failing test on master

There is currently a failed test after merging !580 (merged)

The failure, which can be found by downloading the archive here has the following failure message:

    <testcase classname="testModules.global" name="EposBasics/epos mass" time="0.000" status="run"/>
    <testcase classname="testModules.global" name="Epos" time="0.000" status="run">
      <error message="{Unknown expression after the reported line}">
FAILED:
  {Unknown expression after the reported line}
SIGFPE - Floating point error signal
at /builds/0/corsika/tests/modules/testEpos.cpp:115
      </error>
    </testcase>
    <testcase classname="testModules.global" name="Epos/InteractionInterface - random number" time="0.000" status="run"/>

This corresponds to https://gitlab.iap.kit.edu/AirShowerPhysics/corsika/-/blob/master/tests/modules/testEpos.cpp#L115

  SECTION("InteractionInterface - random number") {
    auto const rndm = ::epos::rangen_();
    CHECK(rndm > 0);
    CHECK(rndm < 1);
  }

It could be that removing the semicolon in Random.hpp caused this...
