Notifications: replace newlines in label-copy because of const char* title

Browse source 
The variable `title` is defined as `const char*`, which means, that
`strchr()` returns a `const char*` as well according to
https://www.cplusplus.com/reference/cstring/strchr/

But in the same line the return value is assigned to a non-const
`char*`, which shouldn't be allowed (error with `-pedantic`).

Because the `lv_label` creates an internal copy of the title sting, just
modify that one instead and replace newline in the copied string.
