Fix minibuffer collapses to one line

Fix minibuffer collapses to one line

It happens since commit SHA:d374afea36df19b5d6b654adc6018b25d6c1d8f2
when resize-mini-windows is set to true.

It also happens when resize-mini-windows is set to 'grow-only (default)
and multiple frames are open.
(Although SHA:435f2b6edfe3ab517c9eda56c6351f0bcfdf3845 work around it)

Temporarily bind `resize-mini-windows' to nil before calling
`read-from-minibuffer'.

Fix #237 and #229

It might fix #77 although this need to be checked as I cannot reproduce it.
