Important: #100135 - Remove cookie warning in ext:felogin

See forge#100135

Description

The cookie warning message in ext:felogin is never shown, since it depends on conditions, which will never be met. The cookie warning message can also be considered superfluous, since a similar message is already shown, if authentication was not successful.

Code affecting the non-working cookie warning message has therefore been removed from ext:felogin. TYPO3 users should remove code from custom templates, which depend on the {cookieWarning} variable.
