Update amount_tests.cpp

[JaredTate]

This PR fixes amount_tests.cpp unit test on Linux. This test passes on mac but not linux because it appears the compilers handle it differently. Seems to be an int32 vs 64 issue. The test worked great for BTC, but not DGB with a larger MAX_MONEY integer.

make check should now pass on all platforms.

To Compile & Run Unit Tests:

  ./autogen.sh
  ./configure
  make -j 8
  make check

Run Specific Unit Test Fixed

cd src/test
./test_digibyte --run_test=amount_tests

Thanks to @Jongjan88 for pointing this out & testing the fix!
