.clang-format: revert two recent changes

- the option 'InsertBraces' might be helpful, however under MSVC it makes much more troubles as it helps: All the time the braces are either inserted in a wrong way or often only the opening brace.
Since we did not use this setting previously, this recent change can be safely reverted for now.

- the 'BeforeElse' change was obviously a mistake in the previous change. All the time we used a linebreak before an else
