[BUG] Lines send before REPL is opened

[raffaem]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When I send line to terminal, with whatever command, for example with

require("toggleterm").send_lines_to_terminal("single_line", trim_spaces, { args = vim.v.count })

the line is send a first time before the REPL is opened, and a second time after it has been opened.

The line should be send only one time after the REPL has opened.

Steps To Reproduce

1. Open a file
2. Send line to terminal

Environment
