Missing text value of comments

[gitarte]

Description
Method GetComments() does not return text value of the comments. It returns only addresses of the cells that have comments

Steps to reproduce the issue:

// load spreadsheet from file
wb, err := excelize.OpenFile(filePath)
if err != nil {
    return result, errors.Wrapf(err, "cannot open spreadsheet %s", filePath)
}

// just printf available comments
fmt.Printf("%+v \n", wb.GetComments())

Example results:

map[
    Sheet1:[
        {Author: AuthorID:0 Ref:I3 Text:} 
        {Author: AuthorID:0 Ref:K3 Text:} 
        {Author: AuthorID:0 Ref:M3 Text:} 
    ]
]

Example of results I expected:

map[
    Sheet1:[
        {Author: AuthorID:0 Ref:I3 Text: some comment text 1} 
        {Author: AuthorID:0 Ref:K3 Text: some comment text 2} 
        {Author: AuthorID:0 Ref:M3 Text: some comment text 3} 
    ]
]

Output of go version:

go version go1.12 darwin/amd64

Excelize version or commit ID:

as in
