Rewrite history test in ShellServerIT

[milleruntime]

There are a few problems with the history test in ShellServerIT. The test should be rewritten to create a table with a unique name and then look for that unique name using the history command.

What I have noticed so far is that the history file isn't properly created inside the IT.

Correction, the history file isn't properly created for the history test. For some reason, tests that use an input, i.e. ts.input.set("name1"), will show up in the history file (the string inside the parentheses that is). This does not work for the history test though. It appears the input has to be used from a command in order to actually show up in the history file.

It does seem that the exec commands do not properly show up in the history file as expected so the IT does not correctly simulate shell functionality that way.
