Added tests for Integer.jl

[Sreevatsa2k]

Adding tests for Integer.jl.

[fieker]

Leave it as it is, it shall be merged as soon as the tests pass.
However, please don't add the line-numbers: the first time s.o. works on the file in Misc, the number will change.
also, next time, the individual tests (@test ...) lines, should be indented (as all the other files)

The file needs a newline

[fieker]

then we can also address the rest

[thofma]

The file is still missing a newline: See the small red circle at the bottom: https://github.com/thofma/Hecke.jl/pull/1351/files#diff-46dcf254ae59dd56207a99849760406fc71dab79d58a7aee8eb534a60eb88d34R18

[thofma]

I think the last thing to do is adding a corresponding line in here: https://github.com/thofma/Hecke.jl/blob/master/test/Misc.jl

[fieker]

unforutunately, you're PR is outdated, some functions names have changed and it needs to get adjusted.
