[QA] Invalid IP-Address should be rejected

[jnweiger]

Seen in 1.2.0-rc.1

According to https://github.com/owncloud/QA/edit/master/Server/Test_Plan_Files_Antivirus.md

• The given example 'localhost%&$#+~' of an invalid hostname is rejected. OK (wait, ... the UI is in English, why does this popup talk German?)

• An invalid ip address, e.g. '127.0.0.1.1' is not rejected. BAD

• The test scan during save reports an error. OK

Expected behaviour:

• both, invalid hostname and IP-Address are handled the same.
• (and after swithcing from German to English + SHIFT-RELOAD in the browser, no German artefacts remain.)

@prsnbrg in https://github.com/owncloud/files_antivirus/pull/540 we now limit top level domain names to 6 characters. This excludes e.g. .international, .company or .university ... I've opened #547 to address this.

Confirmed fixed in 1.2.2-rc.2 (including long TLDs)
