fix:update text bug

[xiongxiongjiang]

fix #104 #78

The reason the UI did not update after the message was updated is due to the author's comparison logic.

UIList.swift

if context.coordinator.sections == sections {
    return
}

MessagesSection.swift

static func == (lhs: MessagesSection, rhs: MessagesSection) -> Bool {
    lhs.date == rhs.date && lhs.rows == rhs.rows
}

MessageRow.swift

static func == (lhs: Self, rhs: Self) -> Bool {
    lhs.id == rhs.id
    && lhs.positionInUserGroup == rhs.positionInUserGroup
    && lhs.commentsPosition == rhs.commentsPosition
    && lhs.message.status == rhs.message.status
    && lhs.message.triggerRedraw == rhs.message.triggerRedraw
}

At this point, we can identify the issue: Although the author included all fields in their response at this link, the MessageRow did not account for one important field. As a result, the comparison of sections showed no changes, which prevented the update from being triggered.

Modification:

static func == (lhs: Self, rhs: Self) -> Bool {
    lhs.id == rhs.id
    && lhs.positionInUserGroup == rhs.positionInUserGroup
    && lhs.commentsPosition == rhs.commentsPosition
    && lhs.message.status == rhs.message.status
    && lhs.message.triggerRedraw == rhs.message.triggerRedraw
    && lhs.message.text == rhs.message.text // add this
}
