AnsiConsole.systemInstall() should only increment "installed" if it succeeds without exception

[kwin]

The counter is incremented first in

jansi/src/main/java/org/fusesource/jansi/AnsiConsole.java

Line 511 in 00e15cb

installed++;

, although exceptions like the following might be experienced:

That leads to the fact that a subsequent call of AnsiConsole.systemInstall() succeeds.
Also it is not possible to call AnsiConsole.systemUninstall in case the exception from above has been experienced as that fails with

java.lang.NullPointerException: Cannot invoke "org.fusesource.jansi.AnsiPrintStream.uninstall()" because "org.fusesource.jansi.AnsiConsole.out" is null

Thanks for reporting, I wonder if you would send a PR to fix this?
