Space after function call followed by variable should not be mandatory

[asyrk]

Related: #733

Input:

$important: ' !important';

@function getColor() {
    @return black;
}

@mixin black() {
    color: getColor()#{$important};
    color: getColor() #{$important};
}

.black-color {
    @include black();
}

Expected output:

.black-color {
    color: black !important;
    color: black  !important;
}

Actual output:

.black-color {
    color: getColor !important;
    color: black  !important;
}

This is partially fixed by #1330 ... but quoted strings get inserted unquoted.
